We all know the 3DS's top screen is magical, but this trailer for new portable title Sudoku Ball 3DS might be stretching things just slightly.

It's not currently known whether WhiteBear Studios' foray into 3D number manipulation will be a cartridge release or available via download, but our money would be on it being one of 3DSWare's first sudoku titles. The first of many, if DSiWare is anything to go by.

Enjoy the trailer below and ask yourself the important question: how did they get the ball to pop out of screen like that?
